This is actually a hard question. It is difficult to determine
the size of a star. If you mean the star with the biggest radius
then it culd be a star like Beutelguese in Orion which is a red giant
that is nearing the end of its life. If you meant the amount of
mass that the star has , it could be a black hole that is very
massive, but not big in size. To determine the radious of a star
we need to measure the brightness, the distance to the star, and th
color. It is hard to know all of these. The color of the star is
a measure of its part int the life cycle of stars.
